Heavy mineral sands are extracted by dredge (Figure 8), bucket-wheel excavators or draglines, and bulldozers.The raw material is then processed, first by gravity concentrators, to remove light minerals; the concentrate is scrubbed and dried, ilmenite, leucoxene, and rutile being removed by magnetic and high-tension techniques (Figure 9).The remaining minerals are then separated …

Fluid separation generates a region of high bed shear stress that can entrain heavy minerals, and a region of low velocity that is a preferred site for the deposition of denser particles. Significant concentrations of heavy minerals, sometimes up to eight times the background value, may be formed by flow separation processes.

Heavy mineral spirals tend to have a higher pitch (and higher descend angle) than those for less dense minerals like coal. Coal spirals that are currently in the market can handle material with a top size of 3 mm, whereas applications for heavy minerals have been limited to a top size of 1 mm (Diketane et al, 2019).
